SPECIFICATION forming part of Letters Patent No. 714,388, dated November25, 1902. Application filed August 15, 1902. Serial No. 119,810. Nomodel.)

To aZZ whom it may concern.- Be it known that I, OSCAR MUSSINAN, acitizen of the United States,residin g at New York, in the county andState of New York, have invented an Improvement in Paper Clips orFasteners, of which the following is a specification.

My invention relates to paper clips or fasteners formed of wire bent tothe required 120 shape and employed for temporarily holding together acollection of sheets of paper; and my inventionfhas for its object toprovide a clip or fastener of this character possessing improvedattaching and clamping facilities I 5 and which when in place will offerno sharp points to engage other adjacent matter.

To this end my invention consists in a clip composed of a single pieceof wire bent to form two central shanks the lower extremities of whichare turned upwardly, forming U shaped end portions, which affordincreased bearing-surfaces, and two side portions or wings extendingoutwardly from said shanks and united at their lower ends by a astraight or curved transverse portion extendclip or fastener embodyingmy invention.

Figs. 2 and 3 are plan views of my clip applied in two different ways tocollections of sheets held together thereby. Fig. 4: is an 4o edge viewof the top of the clip. Fig. 5 is a transverse section on the line 5 5of Fig. 2. Fig. 6 is a vertical section on the line 6 6 of Fig. 2. Fig.7 is a side elevation of the'clip.

In the said drawings, A represents the clip,

5 which is composed of a single piece of wire of suitable hardness andelasticity bent to form two central shanks a a, the lower ends of whichare turned outward and upward, forming two U-shaped portions b b, whichafiord increased or additional bearings at these points for contact withthe surface of the paper. From the upper ends of the shanks a a the wireextends outwardly and downwardly, forming two side portions or wings cc, the lower portions of which converge to the points 5 5 5 5 and areunited by a straight or curved transverse portion 01, which extends overand lies upon the central shanks a a, as shown. The upper portions 6 6of the wings c c are adapted to lie against or adjacent to the edges ofthe sheets to which the clip is applied, as shown in Figs. 2 and 3, andthe U-shaped end portions b 1) form guides to enable the collection ofsheets B, to which the clip is to be applied, to be more readilyinserted and forced between the shanks a a and the overlying wings c cand connecting piece (1, which form the clamping-jaws of the device. Atthe points where the wings join the shanks are formed offsets 7 7, Fig.4., and the wire at these points is given a strong set by subjecting thewire to torsional strain, thereby causing the shanks a a to springtightly up against the transverse piece cl, so that when the clip isapplied to a collection of sheets a strong clamping and holding efieetwill be produced between the bearing-points of the clip. The entire clipis preferably given a slight concavo-convex shape transversely, as shownparticularly in Figs. 1, 4:, and 5, for the purpose of producing anincreased torsion on the wire when the clip is in place, thus increasingits binding or clamping action upon the papers to which it is applied.The clip may be applied to the collection of sheets in such manner thatboth of the shanks a a will lie against the surface of the under sheet,as shown in Fig. 2, or with one shank against the under sheet and theother bearing against the upper sheet, as shown in Fig. 3. By turning upthe lower ends of the shanks a a to form the U-shaped end portions 1) b,as shown, no sharp points are presented to engage other adjacent papersor objects, and the liability of the clip being pulled off the 5 sheetsis thus materially diminished.

What I claim as my invention, and desire to secure by Letters Patent, is

A paper clip of approximately concavo-convex shape transversely,composed of a single 100 piece of wire bent to form two central Iongi-Witness my hand this 13th day of August, tudinal shanks, the iower611C}? of dwhigh are A.
